General description
Percoll® is a classic medium for density gradient centrifugation of cells, viruses, and subcellular particles. Percoll consists of colloidal silica particles of 15–30 nm diameter (23% w/w in water), which have been coated with polyvinylpyrrolidone (PVP). The PVP coating renders the product completely non-toxic and ideal for use with biological materials.
Application
Percoll consists of colloidal silica particles of 15-30 nm diameter (23% w/w in water) which have been coated with polyvinylpyrrolidone (PVP). It is used in cell separation and organelle isolation.
Percoll consists of colloidal silica particles of 15-30 nm diameter (23% w/w in water) which have been coated with polyvinylpyrrolidone (PVP). It is used to establish non-toxic low viscosity, low osmolarity density gradients that can be used to isolate cells, organelles and viruses. It has been used to separate inner and outer membrane vesicles from E. coli. Percoll is isosmotic throughout the gradient, non-toxic, and is easily removed from the purified materials.
Percoll® has been used in sperm preparation to study the energy requirements of bovine embryos.[1]

CAN I FREEZE PERCOLL (P1644)? I SEE IN OTHER REF THAT I CAN, BUT NOT IN THIS REF
1 answer-
This material should not be stored frozen for long periods of time. As per the product information sheet, if stored at –20 °C, gradients form upon thawing, necessitating mixing the contents of the bottle before use. Please see the link below to review the product datasheet for further information:
